Abstract (en)
[origin: EP3496320A1] Embodiments of this application provide a signal transmission method and apparatus. In the embodiments of this application, a first device exchanges reference signal configuration information with a second device, to implement coordinated transmission of a reference signal sent by CoMP user equipment, so that the first device and the second device do not need to separately configure, for the CoMP user equipment, a resource used to transmit the reference signal. In addition, the CoMP user equipment sends a same reference signal to a plurality of devices (including the first device and the second device), so as to reduce delays in obtaining channel quality by different devices, and improve performance of coordinated transmission.
